How the sensor feature works
HOW THE BACKUP SYSTEM WORKS
The Total Control uses non-volatile memory to store watering
programs. This type of memory prevents the watering program
information from becoming lost in the event of a power failure. An
additional benefit of non-volatile memory is that a factory-installed
backup program is not necessary, thereby avoiding the potential for
unplanned operation.
Because the current time and date are always changing, only the most
recent date can be saved in non-volatile memory. Therefore, a battery
is required to maintain the correct time and date in the event of a
power failure. A 9-volt alkaline battery (not provided) will maintain
the correct time and date during power failures up to 90 days. In a
typical installation, the battery should last from two to four years
before replacement is necessary. Once the battery or AC power is
connected, the controller can be fully programmed for operation.
Note: For operation of the valves, AC power must be applied.
To install the battery:
Figure 3
1. Unlatch the hinged control module
assembly and carefully swing it
outward to open.
2. Locate and remove the battery
compartment cover from the lower
back side of the module. See Figure 3.

4. Insert the battery into the
compartment and reinstall the battery compartment cover.
Caution: Batteries contain hazardous material. Always handle and
discard batteries properly in accordance with the battery
manufacturer’s recommendations.

General Information
HOW THE ELECTRONIC CIRCUIT
BREAKER WORKS
The controller is equipped with an electronic circuit breaker. If the
controller detects a short circuit, the affected station(s) will be turned
off automatically. The display will then flash “SHORT” and the shorted
station number or “MASTER VALVE.” The controller continues to
automatically water the other stations and the following watering
programs until the shorted station is repaired. The program will be
cancelled if the master valve circuit is shorted. Each automatic start
will attempt another cycle and retest the short-circuited valve.
Listed below are the most common conditions which will activate the
electronic circuit breaker. After correcting the problem, return the
controller to normal operation as follows:
1. Set the dial to one of the following positions: Run
Manual-Single Station or Manual-Program Cycle.
,
2. Press the OFF button to return the controller to the normal
operating mode.
Condition: The word “SHORT” displays with one or more station
numbers.
Diagnosis: One or more stations are shorted.
Solution: Check the wiring of the displayed stations for the cause
of the shorted condition. Repair valve(s) and/or wiring
as needed.
Diagnosis: Too many valves operating at the same time causing an
overload condition.
Solution: Check watering programs for concurrent station
operation. Include master valve/pump start relay if used.
Maximum total output is 24 V a.c. at 1.25 amps. Reduce
the number of stations running at the same time.
Condition: The word “SHORT” displays without any station
numbers.
Diagnosis: A short circuit has occurred with a time duration too
short for the controller to determine the station.
Solution: Check all valve wiring for breaks in the insulation
which may cause a station output to short to common.
Diagnosis: A transient power surge spike has occurred.
Solution: Reset the controller.
Diagnosis: A short or overload occurred on one watering cycle but
was no longer there on a subsequent cycle.
Solution: Check for loose and/or exposed valve wiring.
General Information

HOW THE SENSOR FEATURE WORKS
The Total Control is equipped to operate with an optional rain
sensing device (rain switch) to prevent automatic controller operation
during rain.
The rain switch is a simple device, typically installed on a roof
overhang or stationary structure exposed to rainfall and full sun, and
shielded from irrigation spray.
When rain occurs, the normally-closed rain switch senses the moisture
and opens the valve common circuit, effectively preventing all output
to the field. The electronic programming portion of the controller is
isolated from the rain sensor switch, and continues to operate as
programmed. When rain stops and the rain switch returns to its
normally-closed state, the valve common circuit is restored, enabling
watering to resume as scheduled.
A two-position sensor switch (see item 18 on page 3) is provided to
enable you to easily bypass operation of the the rain switch at any
time. If you choose to disregard rain switch input, place the SENSOR
switch in the Bypass position. To enable rain switch operation, place
the Sensor switch in the Active position.
IMPORTANT: If a rain switch is NOT connected to the
controller, the SENSOR switch MUST be in the BYPASS
position to enable controller operation.
The controller will not operate automatically or manually if the
SENSOR switch is in the ACTIVE position without a rain switch
connected.

PROGRAMMING THE
CONTROLLER
This section covers the following topics:
• Getting started
• Setting the current time and date
• Erasing any prior programs
• Setting the station run time
• Selecting Master Valve/Pump Start on/off
• Setting the program start times
• Selecting the days to water
GETTING STARTED
PREPROGRAMMING THE CONTROLLER
The unique design of the Total Control enables you to easily remove the
control module from the cabinet for convenient programming while in the
comfort of your home.
To take advantage of this feature, unlatch the control module and swing it
outward. Disconnect the ribbon cable, then simply unclip the module from
its support frame. Now, by installing a 9-volt alkaline battery (as shown on
page 4), you can program and review your watering schedules and have the
controller ready to operate immediately upon completion of the
installation procedures.
Note: To extend battery life, the display will automatically dim after two
minutes of inactivity. To restore the display, simply turn the function dial
to any position. A fresh battery will maintain the current time and date for
over 2000 hours of continuous duty. The program memory is non-volatile
and does not require a sustaining power source for retention.
WHAT IS A WATERING PROGRAM?
A watering program is basically a small set of instructions which tells the
control module when to start a watering cycle, which stations to operate
during the cycle, which days the cycle will be active and how long each
station will operate during the cycle. The Total Control has four
independent watering programs available for your use. Although only one
program is required to operate your controller, using separate programs
enables you to optimize the amount of water being applied to different
areas of the landscape. For example, you might use one program to water
lawns in full sun every day. Another program could be used to water lawns
in partial shade only on Monday, Wednesday and Friday. Trees and shrubs

using drip irrigation could run on a separate program once every two weeks.
The garden area requirements might include watering every other day.
To take full advantage of the programming options available, it is
important to first understand how the controller works during operation.
The following section explains what a watering cycle is and provides a
basic example of how multiple programs can be set up.
WHAT IS A PROGRAM WATERING CYCLE?
When a watering start time is selected, that time becomes the beginning
of an automatic watering cycle. A watering cycle operates each station
assigned to the program, one by one, in numerical order.
In the following example (also shown on the sample watering plan on
page 9), we have set up Program A to start at 2: 00 a.m. and again at
3:00 a.m. on a 1-day interval (every day). Stations 1, 2, 4 and 5 are front
and back yard lawn areas which get full sun throughout the day. Each
station will run for 10 minutes per watering cycle, for a total of 20
minutes run time per day. Stations 3, 6 and 7 are lawn areas which are
shaded during the afternoon hours. These areas require less water, so we
have assigned them to Program B and programmed them to run once for
20 minutes on a 2-day interval (every other day).
At 2:00 a.m., Program A watering cycle starts. Station 1 turns on, runs for
10 minutes, and shuts off. Station 2 turns on, runs for 10 minutes, and
turns off. Stations 4 and 5 operate sequentially in the same manner, each
running for their set run time. When Station 5 shuts off, the watering
cycle is completed for the first start time. At 3:00 a.m., the watering cycle
starts again and repeats the same station-by-station watering sequence.
Note that we have 40 minutes total operating time per cycle in
Program A. If we had set the next start time at 2:30 a.m., the start time
would have been delayed until 2:40 a.m., enabling the first cycle to finish
as programmed. This function is called “start time stacking”, and can
occur within each program.
Watering programs, however, operate independently, which means that
two or more programs can run simultaneously. In our example,
Program B will also start at 2:00 a.m. Therefore, Stations 1 and 3 will
turn on at the same time, and Station 2 will turn on while Station 3 is
running. This feature enables more watering to be completed within the
prime “watering window”, which is generally between Midnight and
6:00 a.m.
Note: When scheduling watering programs to run simultaneously, it is
important to ensure the water supply has sufficient pressure and volume
to maintain optimum sprinkler performance.

SETTING THE CURRENT TIME AND DATE
Before you can program the controller for automatic watering, you must
set the controller clock to the current time and date. This controller
features a 365-day calendar with automatic leap year compensation. Once
the date is set, the controller keeps track of the date and enables troublefree, odd-even day of the month watering required in some locations.
The time and date apply to all programs. To set the time and date, follow
the steps below.

ERASING ANY PRIOR PROGRAMS
This process enables you to easily clear the controller memory of all
user-defined watering program information within an individual
program. This is an optional procedure and can be skipped if you wish
to retain previous program operating information or the controller has
not yet been programmed.
Erasing a program resets the memory to factory conditions: No station
run time, program start time or active watering days. Water Budget is
set to 100% and Master Valve/Pump Start is set to be “On.”
Note: This process is program independent and resets only the
information for the selected program.
To erase program information for a selected program:
1. Select Program A, B, C or D with the Program switch.
2. Turn the function dial to the Program Erase position. The display
will show “ERASE.”
3. Press and hold the OFF button until “DONE” is displayed.
4. Repeat this procedure for each program you wish to erase.
SETTING THE STATION RUN TIME
A station is assigned to a program when it is given a station run time
(from 1 minute to 10 hours) in that program. The station can have only
one run time per program. Additionally, the station can be assigned to
any number of programs and have a different run time assigned in each.
To set the run time for each station:

5. Repeat steps 3 and 4 to set a run time for each station you wish to
assign to the selected program.
6. Repeat steps 2 through 5 for each program as necessary.
MASTER VALVE/PUMP START ON/OFF
The Total Control enables automatic operation of the Master
Valve/Pump Start output circuit to be controlled independently for
each watering program. For example, if a program is used for drip
irrigation and the system pump is not required, the Master
Valve/Pump Start output circuit can be shut off whenever that
program begins operation.
The factory setting is ON for each program. Use the steps below to
select the operation of this feature for each program as necessary.
1. Turn the function dial to the Station Times

4. Press the OFF or ON button to display the operation of the master
valve/pump start output for the selected program.
5. Repeat steps 2 through 4 for each program as necessary.
SETTING PROGRAM START TIME(S)
This procedure is used to set the watering cycle start time(s) for each
program. A maximum of 16 start times can be allocated to the four
programs in any manner. Each start time will initiate a sequential
watering cycle of all stations with an assigned run time in the program.
Note: When 16 start times have been allocated, the display will show
NONE REMAINING when attempting to assign additional start times.
To set program cycle start time(s):
1. Turn the function dial to the Program Start Times
position.
2. Select Program A, B, C or D with the Program switch.
3. Use the + and/or – buttons to display the start time.
Note: To remove a start time, adjust the time to display OFF
(located between 11:59 p.m. and 12:00 a.m.).
4. Press the NEXT button to assign another start time to the
program.
5. Repeat steps 2 through 4 for each program as necessary.
12
Programming the Controller
Note: The Total Control will operate one watering cycle in a program
at a time. If a start time occurs while a watering cycle is in progress,
the start time will be delayed until the previous cycle is finished (this
is called “start time stacking”). If the watering cycle extends past
midnight into the next day, the cycle will continue operating until
finished. However, if a watering cycle has been delayed until after
midnight into a non-watering day, the watering cycle will not occur.
SELECTING THE DAYS TO WATER
Several watering day scheduling options are available. Each watering
program can utilize any ONE of the following schedules:
• Days of the week
Use this type of schedule to water on specific days of the week. The
days are displayed as three-letter abbreviations. For example, Sunday is
SUN, Monday is MON, etc. Only the days you select to water will
remain on the display.
• Odd Days or Even Days
To select every odd or even number calendar day, use this option.
Because the 31st and the 1st are both odd number days, the 31st is
automatically removed from the schedule. This watering day option
also enables selected days of the week to be removed from the
schedule.
• Day Interval
Selecting watering days by Day Interval enables a specific number of
days between watering to be selected. For example, selecting a 1-day
Interval schedules watering for every day. A 2-day interval schedules
watering for every other day. A 30-day interval is the maximum
interval frequency, which provides watering once every 30 days.
Another setting within the Day Interval is the current day of the
schedule. The current day (displayed as TODAY) can be set for any day
within the interval. This number automatically increases by one every
day. When the TODAY number equals the Day Interval number, a
watering day will occur. For example, to water every third day starting
today, a 3-day interval would be set with TODAY as day 3. Or, to water
every 5 days starting tomorrow, a 5-day interval would be selected with
TODAY as day 4.

Water Budget
Manual Operations
Off and Rain Delay Modes
WATER BUDGET
The Water Budget feature enables you to easily increase or decrease
the station run time (by percentage) of all stations assigned to a
selected program. This is handy for making temporary, overall station
run time adjustments without changing the original run time settings.
Water Budget values range from 0 to 200% in 10% increments, with
100% being the normal setting.
For example, as the fall season approaches and the temperature
decreases, you may want to reduce the station time for the stations in
program A by 30%. Later you can return station times to their original
values by setting the Water Budget value back to 100%.
Note: It is possible to inadvertently cause start time stacking when
increasing station run time. Careful planning and use of Water Budget
will prevent this from occurring.
To change the Water Budget percentage value of a selected program:
1. Turn the function dial to the Water Budget
position.
2. Select Program A, B, C or D with the Program switch.
3. Use the + and/or – buttons to increase or decrease the percentage
value (0–200%).
4. Turn the function dial to the Run
position.
Note: The controller displays the % symbol in the Run
position when Water Budget is in use for any program. During
operation, the adjusted run time will be displayed.

MANUAL OPERATIONS
Manual operation allows you to run individual stations or start
automatic watering programs as needed. The Total Control provides
separate dial positions for each type of operation: Single Station and
Program Cycle.
SINGLE STATION
This option enables individual stations to be operated for an untimed
duration (turned On/Off) or operated for a selectable duration from
one minute to 10 hours.
1. Turn the function dial to the Single Station position.
2. Select Program A, B, C or D with the Program switch.
Note: The programmed status of the master valve/pump start in
the selected program determines whether the master valve/pump
start will be activated with the manual operation .
3. Use one of the following options to operate the station.
For untimed operation:
A. Press the NEXT

INSTALLATION PROCEDURES
This section includes instructions for mounting the controller cabinet
and making the necessary wiring connections. To ensure safe
operation, it is important to follow the instructions carefully.
SELECTING AN INSTALLATION SITE
Selecting the proper installation site for the controller is essential to
safe and reliable operation. The outdoor model features a weather
resistant cabinet designed for indoor or outdoor installation. The
indoor model is not weather resistant and must be installed indoors
only.
The controller should be installed on a vertical wall or other sturdy
structure near a grounded power source. For outdoor models, select a
location that shades the controller during the hottest hours of the day
and provides as much protection from direct sunlight, rain, wind and
snow as possible. DO NOT mount the controller where it will be
exposed to direct spray from the irrigation system.

Installation Procedures
CONNECTING THE VALVE WIRING
1. To provide a field common wire, attach one wire to either solenoid
lead of all sprinkler valves and master valve (optional).
2. Attach a separate control wire to the remaining solenoid lead of
each valve. Label the control wires with the intended station
number for identification at the controller.
Caution: All wiring splices must be waterproofed to prevent short
circuits and corrosion.
Caution: A maximum load of 12 VA (0.5 amps) may be connected
to each station. A maximum load (including master valve) of 30 VA
(1.25 amps) may be programmed to operate simultaneously.
Exceeding these limits can damage the controller.
3. Route the control and common wires into the controller cabinet
through the bottom access opening. Remove approximately
1/2" (13mm) insulation from the ends of each wire.
4. Attach the field common wire to one of the three valve common
terminals labeled “VC.”
5. Referring to Figure 6 connect each valve control wire to the
appropriate station number terminal. If an optional master valve is
installed, connect its control wire to the terminal labeled “MV.”
Tighten all terminal screws securely.

CONNECTING A PUMP START RELAY
When a pump is to be operated by the controller, a compatible relay
must be used. The relay coil will be connected to the master valve
(MV) terminal and must be rated for 24 V a.c. at 0.5A maximum. The
relay contacts will be connected to the pump start terminals and must
be rated for use with the particular pump.
Note: Transient suppressors may be needed across the relay contacts
in installations using large pumps.
Caution: Do not connect the master valve output terminal directly
to the pump start terminals. This will damage the controller.
To connect the pump start relay:
1. Connect the master valve output terminal (MV) to one side of
the relay coil.
2. Connect the other side of the relay coil to the valve common
(VC) terminal. See Figures 6 and 7.
WARNING
Proper connection of the pump and relay contacts
depends on the pump configuration and may involve
HIGH VOLTAGE. This connection should be performed by a licensed electrical contractor in
accordance with all requirements of the National
Electrical Code, applicable state and local codes and
the pump manufacturer’s recommendations.

CONNECTING AN EARTH GROUND
A power surge is a sudden rise in voltage on the power main line. It is
then often followed by a drop in voltage as the power line equipment
tries to protect area users. A lightning strike on the power grid is the
most common cause of power surges and can be damaging to the
controller. *Surge protection is built into the Total Control PC board
to reduce the potential for surge damage by shunting the voltage to
earth ground. Therefore, an important step in the installation process
is to properly connect the controller to an earth ground source,
especially if the controller is located in a lightning-prone area.
*Note: The Total Control international units are manufactured
without output surge protection. If output surge protection is required,
contact your local Irritrol Systems dealer for assistance.
Caution: The built in surge protection components cannot
effectively protect the controller circuitry from power surge unless
properly connected to an earth ground source.
To connect an earth ground:
1. Route a 12–16-gauge (2.0–1.0mm2) solid copper wire in the most
direct path from the “EARTH GND” lug, located on the controller’s
terminal board (see item 21 on page 3), to an earth ground source
such as metal (not plastic) water pipe or copper-clad ground rod.
2. Clamp the bare wire securely to the pipe or ground rod. Make sure
the wire contact area is free of dirt and corrosion.
Installation Procedures
23
CONNECTING THE POWER WIRES
The outdoor controller has a built-in transformer which must be
connected to a grounded three-wire 120 V a.c. (domestic), 230 V a.c.
(international) or 240 V a.c. (Australia) power source.
WARNING
All electrical components must meet applicable national and local
electrical codes including installation by qualified personnel.
These codes may require an external junction box mounted on the
transformer nipple and a means in the fixed wiring of disconnecting
AC power having a contact separation of at least 0.120" (3mm) in
the line and neutral poles.
Ensure the AC power source is OFF prior to connecting to the
controller.
The wire used for connection to the controller must have insulation
rated at 105°C minimum.
Note: Power connection for indoor controller is discussed on page 19,
steps 9 and 10.
Caution: Do not connect the controller to one phase of a threephase power supply used by a pump or other electrical equipment.
1. Ensure the power is disconnected at the source.
2. Route the AC power and equipment ground wires through electrical
conduit to the controller.
3. Using a proper wire connection method, attach the Hot (Line 1)
to the Black wire, Neutral (Line 2) to the White wire and
Equipment Ground to the Green or Green/Yellow wire.
Note: The wire connection method shown in Figure 9 applies to
a domestic controller installation
only. For international controller Figure 9
